Apparatus and Method for eleminacion Waste moulding and rectification of Railway Wheels

摘要

A method and apparatus (10) for grinding cast steel railroad wheels (34) is provided. The apparatus (10) comprises a railroad wheel support assembly that includes a roller assembly (62,64,100,110) to receive and grasp the railroad wheel (34) and rotate the railroad wheel (34) about its center axis. A grinding assembly is also provided that includes a motor (160) operatively connected to a grinding wheel (168). The motor (160) and grinding wheel (168) are mounted to a support assembly (122). The railroad wheel support assembly oscillates about an axle assembly (70,72) during grinding. The grinding assembly is designed to advance the grinding wheel (168) laterally into the railroad wheel during grinding. The lateral advancing of the grinding wheel (168) and oscillating of the railroad wheel (34) are controlled to achieve a finish grinding of the selected surface of the railroad wheel (34) to a preselected contour. The railroad wheel (34) may be ground when it has cooled from its initial casting temperature to a temperature of about 425 - 650 DEG C. IMAGE
